Ferrari plan to shut down and recalibrate their ageing Formula One wind tunnel after blaming it for a series of failed updates this season. Team principal Stefano Domenicali said they had found some of the aerodynamic developments produced to keep championship leader Fernando Alonso's car competitive had worked in the tunnel but not on the track. He told a news conference at the Japanese Grand Prix that the windtunnel was not obsolete but not as advanced as those of its rivals.
